    About AAC Audio Format

    AAC (Advanced Audio Coding) is a lossy audio compression format designed to be the successor to MP3. Developed by the MPEG group, AAC achieves better sound quality than MP3 at similar bitrates. It's the standard audio format for YouTube, iTunes, PlayStation, Nintendo, and Android devices.

    • Quality: Transparent quality at 128 kbps for most listeners
    • Flexibility: Multiple profiles for different use cases
    • Modern: Supports latest psychoacoustic models
    • Scalability: From low bitrate speech to high-fidelity audio

    AAC Profiles

    • AAC-LC: Low Complexity, most common profile for general use
    • HE-AAC: High Efficiency, optimized for low bitrates
    • HE-AAC v2: Enhanced efficiency with parametric stereo
